In all seriousness, really nice platformer! Something I've found frustrating about some games in the jam is a lack of clarity. Your game was super clear. Key + door = win level. And then the guard NPC was beautifully clear: move into the triangle LOS, you lose. Solid design in that regard. You might be interested in adding coyote jumping and/or jump buffering to your game logic. I just learned how to code it myself. It's pretty easy to implement but it adds a ton of quality of life for platformers with a lot of jumping. This is a good read about it: https://developer.amazon.com/blogs/appstore/post/9d2094ed-53cb-4a3a-a5cf-c7f34bc...
Nice work!
